To all'whom tmay concern: j j bolts. extend and, after the nuts l1 are se- Be it lrnown that I, JOHN VOLFE, a citicured onto the bolts, portions of the said zen of the United States of America, residf plate, as shown at 13, are bent up at the sides ing at Cleveland, in the county of Cuya of the said nuts and thereby prevent their hoga and State of Ohio, have invented certin-ning. 55 tain new and useful Improvements in Rail! l A shaft Or bolt 15 extends between the Joints; and lf hereby declare the following l heads 7 of the bolts 6 and the ends thereof to be a full, clear, and exact description of Xtend through the openings 8 in the heads the invention, .such as will enable others t 7. The shaft or bolt l is preferably proskilled in the art to which it pertains to l vided at one end with a head 1G and at the 60 f make .and use the same. opposite end with a small opening` 17 which This invention relates to new and useful is adapted to receive a pin18 which Vlocks` improvements in rail-joints and particuthe said bolt against longitudinal movement. larly to an -improven'ient on a joint of the The bolt 15 is also provided with fins l) type set forth and described in my applinear the head thereof which fit into the re 65 cation Serial No. 460,432.v cesses 9 in the heads of the bolts 6 and there The object of this invention is to provide l y prevent the shaft or bolt from roa rail joint which while embodying all the tating.

advantages of theA joint described in my On the shaft or bolt lis mounted a earn application above referred to will be more block 20.k rhe face of this cam block 2O 70 simple in construction and more positive l iS curved eccentric to both the axis of the in action. cam and the axis of the supporting sha-ft 15,

My invention therefore consists in the curving outwardly and downwardly from features of construction and combination of the top edge of the cam face so that the face parts described in the specification, pointed ofthe cam has its greatest eceentricity near 75 out in the claims and illustrated in the acthe lower end of the cam face. The Cain companying drawings. j face is also out away at its lower edge to n the accompanying drawings Figure 1 form a shoulder 21. In the wall of the bore s a top plan of a joint embodying my inof the cam block is formed a longitudinally ven'tion. Fig. 2 is a side elevation of saine. eXtending recess 23. This recess is deepest 80` Fig. 3 is a section on line lm, FigjQ. at its top and in the deep portion thereof gain referring to the drawings, 3 repreis arranged a pin 24. It will be understood sents rails of the usual construction with that as the cam block Q0 rotates downwardly their' ends abuttin to form a continuous I the pin 24 will be in the deep part of the said' Section of track. t each side of the rails, recess, leaving the cam block free to rotate at the joint, are arranged fish-plates 4f of' downwardly, but in case the cam block the usual construction so as to span the should for any reason be given an in'ipulse joint and overlap' the ends of the rails at which would tend to rotate the cam up each side of the joint. Bolts t3 are passed wardly, then the pin 2l will move into the through the fish-plates andthe abutting ends l shallow portion of the recess 23 and there- 90 of the rails. The said bolts are provided Y by lock the cam block 2O to the supporting with enlarged heads 7 in which are formed j shaft 15 and prevent any upward movementl openings 8 which have small recesses 9 thereof. y communicating'therewith. The bolts 6 have Between 'the cam block 20 and the adjathe usual screw-threaded ends arranged to cent tish-plate is arranged a resilient loekreceive nuts 11' of the usual construction. ing wedge. This looking' wedge is arranged Any suitable locking device may be proto extend across the entire face of the cam vided for holding the nuts against movement and preferably formed by bending or and as shown said locking device consists j doubling up a resilient sheet or plate in `the of a plate 12 through which the ends of forni of the letter U, and thereby forming 100 two divergent members 27 and 28, and also al1-extension or toe-piece 29. The space between the members 27 and 28 lis preferably filled with a suitable elastic material v30 such as a hard rubber,composition which reinforces the resilient action of the members 27 and28.

In assembling the joint it will be understood that the fish-plates are rigidly clamped to the rails bj1 tightening the nuts ll on the1 ends of the bolts- 6 in the usual manner. The cam block 20 is then mounted between the heads of the bolts 6 by means of the shaft l5, but before the cam is turned down into its operative position the resilient wedge is inserted between the cam block and the adjacent fish-plate with the toe-,piece of the wedge under the shoulder on the 'face of the cam block, and then the cam block is turned in and down thereby forcing down the resilient wedge. The forcing down of the resilient wedge will cause the two 'divergent members thereof to approach each other so that the wedge will be under considerable tensionv and in case the bolts 6 stretch or elongate the said wedge will exv pand and the action thereof will draw the olts 6 through the rails and the fishlate so that the nutsbn the bolts will vbe eld tightly against the fish-plate adjacent .thereto.' If there is more stretch to the bolts 6 than can be taken care of byfthe simple expansion of the divergent members of the wedge then the wedge will move ldown farther lbetweenA the cam block and the fish- 'plate, the shape of the curved face of the cam allowing the cam block to rotate down vfreely as thewedge moves downward.
